Abstract (en)
[origin: US2017288753A1] Each of a plurality of signal measurement circuits is included in a terminal. Each measurement circuit receives a signal from a transmitter in a satellite and measures characteristics of the signal. A computer is programmed to receive data from the signal measurement circuits. The data indicates characteristics of the signal, including a strength of the signal. The computer determines an initial estimated satellite pointing direction, and generates subsequent estimated satellite pointing directions. For the initial and subsequent estimated pointing directions, the strength of the signal received by each measurement circuit is compared with an expected strength of the signal based on the respective estimated pointing direction. Each subsequent estimate is based at least in part on the comparison of the immediately preceding estimate. Based on the comparisons, the computer estimates a current satellite pointing direction.
